In the circuit of let VDD 5 5 V, Vtn 5 2Vtp 5 1 V, kp 5 40 A/V2 , kn 5 400 A/V2 , and assume n 5 p 5 0 for simplicity. (a) Find the point Q0 on the VTC at which vO 5 vI . Hint: exploit the fact that iDp 5 iDn. (b) Replace the FETs with their small-signal models to estimate the gain voyvi at Q0. Hint: in the triode region, the pMOSFET acts as a suitable dynamic resistance rsd.
